Keys to an energy efficient home


I was at an event a few weeks ago that focused on making existing homes energy-efficient. One attendee pulled me aside to discuss what else she could do in her home. SO I asked the basic questions, “have you had an energy audit?” Her answer was immediate and definitive, my house is very energy-efficient. So I followed up with, “what kind of insulation do you have?” Her answer made me wonder where this conversation was heading “the normal kind.”

Most houses that are built don’t take building science into account. I believe this is in large part because you cannot see many of the things that are important for energy efficiency. So what should you look for in your home to determine if you are really energy-efficient?

Get to know your home, look at the insulation in the attic, crawl space / basement, determine what kind of windows you have, and know the age and efficiency of your HVAC system. Then talk to your neighbors and friends about how much they pay per square foot for electricity. When you host a dinner party, show your friends the things that you have done to reduce your energy bills and talk about what they have done. Call a building scientist (me) to discuss all the low-cost things that you can do to make your home more energy-efficient. We all need to find ways to spend less each month – if you have not made your home efficient, then you are losing money every month that you could be saving!
